APG stocks the V3X211, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 211 mm (8.307 in), a cross section of 3 mm (0.118 in), and an outside diameter of 217 mm (8.54 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Expect good resistance to many acids, aromatic hydrocarbons, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.
Common environments for this compound include automotive fuel systems, aerospace, and oil and gas.
Stocked as V3X211 and sold individually. Unit weight is approximately 8.8643 g. Review your operating media and conditions against this specification before installation.
